Communications procedures

  32 The master should ensure that an authorized person responsible for communications is on duty at all time when the ship is in, or approaching, areas where attacks occur. It should be ensured that ship-shore communication methods are tested and report intervals agreed prior to entering the high-risk area. The frequency of reporting should be maintained.

  33 Shipowners should report attacks and attempted attacks to any national, regional or subregional reporting systems made available by Governments, including those run by security forces.

  34 Where possible, ships raising alerts should specify that an act of “piracy/armed robbery” is in progress, in line with other distress categories such as “sinking” or “on fire”. This could have a potential to improve the alerting process and speed of response.

  35 Prior to entering areas where attacks have occurred and where the GMDSS installation on board does not have facility for automatically updating the “ship position” data from an associated electronic navigation aid, it is strongly recommended to enter the ship’s position at regular intervals into the appropriate communications equipment manually. It is recommended that owners initiate the GMDSS INMARSAT “C” alarm programme before entering affected areas for use when appropriate.

  36 When entering waters where piracy or armed robbery activities have been reported – especially if the AIS is turned off for security reasons – the ship should routinely transmit its position to the shipping company at given intervals, thereby giving the shipping company a first notice that something is amiss if the transmissions are interrupted. Masters should act in accordance with the guidance in resolution A.917(22) on Guidelines for the onboard operational use of shipborne automatic identification systems (AIS) and resolution A.956(23) on Amendments to the guidelines for the onboard operational use of shipborne automatic identification systems (AIS) (resolution A.917(22)) concerning the turning off of AIS. In the event of an attack, masters should ensure to the extent feasible that AIS is turned on and transmitting to enable security forces to locate the vessel.
